Default Delco 600 Overkill

Well I got the thing to run and run really well... And I see 10amps on the meter and 50 some vdc being crammed into the three 12 volt batteries, is there some way to dial it down? I watch half waiting for the acid to boil out and the battery to melt and catch fire that the amps did come down as they did get charged up but I know that is got to me too much output.. any thoughts to back off the power

Do you have a variable resistor in regulator circuit, or a “high voltage” cutout relay?
About 42v is as high as you should go charging a series string of three 12v batteries. More is likely to boil off electrolyte as you state.

I don"t think those engines have a governor? Instead they're designed to shuf down at around 40 volts (for a 16 cell, 32 volt nominal battery). Sounds like fhat component is either missing or not working.

Alternatively, you could apply enough load to keep the voltage down and allow the set to run as long as you like.

Another thing to consider; is that these were primarily for charging the battery bank, once it was run down. For example, the only time you would run this is when you used an electric motor, or iron. They had enough draw to nearly match what it was putting out. Sometimes it would get run only once a week depending on how much battery was used for lighting.

Try a resistive load on the line side, and see what it does....

Thumbs up Re: Delco 600 Overkill

Thanks folks I can look into all options.. I have not found anything in the wire diagram for any kind of or resister.. I do know the manual self start thing can be a pain.. but I enjoy it never the less.. I do have an old porcelain screw in heater which should make the thing tone down.. perhaps that might have to be installed.. now for the million dollar question.. on the battery side or the line side.. currently the set up is just the batteries.. thoughts?

Sorry just reread the replys.. I can wire in that heater on the line side and see what happens..

your problem is running 3 12v batteries on a 32v system. Remove 1 12v battery and replace with an 8v battery. You will find that your charge voltage going into the batteries will drop drastically. Usually around 38-42 volts. Thus solving your problem. TSC/rural king has choices on the necessary 8v battery. DELCO'S WERE NOT DESIGNED TO RUN ON 36VOLTS. Running on 36v will also effect the RPM of your unit. Hope this helps.
